To all whom t may. concern: l

Be it known that I, EDMUND C. MORGAN, aV citizen of the United States, residing at Morgan Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Mining-Machines, of which the following is a specification.

This invention relates to mining machines, and more especially to that type of mining machines which are movably supported so that they may be driven intol the drift or tunnel.'

The primary object of this invention is to provide an improved construction, combination and arrangement of parts in a mining machine.

One of the objects of the invention is to.

provide improved means for cutting the coal or other material into slabs.

Another objectv is to provide improved means for feeding the machine to its work.l Another object is to provide improved means for adjusting the height of the out? ters.

Other and further objects will appear in I the speciication and be more specifically pointed out in the claims, reference being had to the accompanying drawings exemplifying the invention, and in which- Figure 1 is a side elevation of a mining machine constructed in accordance with the principles of this invention. Fig. 2 is a top plan View of the same. Fig. 3 is a rear end elevation of the same. Fig. s is a top plan view of the rear portion of the machine, parts being removed and parts broken away. Fig. 5 is a section on the line V-V of Fig. 4. Fig. 6 is a section on the line Vif- VI of Fig. 4. Figi 7 is a detail side elevation of a side arm and the movable base of the inachine. Fig. 8 is an enlarged detail elevation of parts shown in Fig. 7. Fig. 9 is a section on the line IX-IX of Fig. 8. Fig. 10 is a top yplan fragmentary vicw'of a portion of the the drawings, and first to Figs. el, 5 and 6,

the main truck frame of themachine com prises side rails 1 and 2 rigidly united, at

' their forward ends by aI cross rail 3 and having rotatably-:mounted in suitable bosses-,amounted upon 'reclprocablesupports 34C (see Figs. "l and 6) provlded each with an adand 6 odset from their rear ends, a shaftfi' the same. Fig. 12 is a diagrammatic.

constructedin two sections. ln order to provide a suitable platform or base which may be moved upwardly and downwardly, a base member or platform 8 is provided with rearwardly projecting arms 9 and `10 which are journaled on the drive shaft 7, thus'- adapting said platform 8 to be raised and lowered by an angular movement about said shaft. To impart this movement, a set screw 11 impinging upon the cross rail 3 is preferably employed, but any other suitable means may be employed for this purpose. Rigidly mounted upon the platform 8 is a motor 12 of any suitable design, said motor preferably being a reversible electric motor. A motor shaft 13 has keyed to its upper end a driving pinion 14 which meshes with a gear 15 keyed to the upper end of a vertical shaft 16. A worm 17 keyed to the lower end of the shaft 16 meshes with a worm wheel 1S keyed to a shaft 19, said shaft 19 being also provided with gears 20, 21 keyed thereto adjacent either end. The shaft 19 is preferably rc tatably mounted in the bearing brackets or arms 22, 23, which form integral projections from the rear ends of the arms 9 and 10. The gears 2O and 21 mesh respectively with gears 24: and 25 free to rotate upon the respective sections of the shaft 7, whose sections are adapted to be rotated relatively to each other by having adjacent ends provided with a connecting sleeve 26. Each of the gears 24 and Q5 is provided with a clutch element, as shown in Fig. 3, while splined upon each section of the shaft 7 is a. clutch 27 which may be moved into and out of engagement with the clutch element of either of said gears 21 and thus throwing the motor into driving connection withthe rcspective sections of thev shaft 7. To adapt said clutches 27 to be operated independ ently of each other, shifting levers 28 and 29 of the ordinary and well known construction are provided operatable preferably by hand. Upon the outer end of each of the shaft sections 7 is keyed a driving sprocket 30, which engages a pecl-chain 31, the forward end of each of said pcd-chains, which areendless, being supported by a sprocket 32. Carriedby the pcd-chain 31 are aplin rality of feet or peds 33 adapted to impinge upon and grip the floor of the mine. To provide means for regulating the tension in the pcd-chain 31, the-"forward sprockets 32 are i j ing atlts-top a bearing 47 1n axial. alinerig. i).

.hub portion justing screw 35 havingiits headbearing bearing base or support 38 (see particularly Fig. 1) for rotatably mounting a vertical cutter bar shaft39.' The upper end of the cutter bar shaft39isfrotatably mounted in the `forward end of a bracket arm 40 (see Figs 1 and 2) which projectsjlaterally from a vertical support orvbase `41 suitably mounted upon the platform or base member 8. Projecting forwardly from the'housing of the motor l12 are a pair of bearing brackets or arms 42 and 43 provided with suitable bearing bosses for y mounting the vertical shafts 44 and 45. The upper bracket 42 is provided with an extension 46 for support mentwith other bearings 48 and 49 (see Rotatably journaled in the bearing bosses 47, 48 and .49 is an adjusting screw 50, upon which are mounted the hubs of a plurality of intermediate cutter bar supports 51. In order to raise and lower the intermediate cutter bar supports 51, the hub portions of said supports are in abutment with threaded nuts 52,'which may be rotated by Spanner Awrenches on the screw 50,

and so causedto travel upwardly and downwardly. The vdetail construction of each of the cutter bar 'mechanisms maybe understood. from an inspection of Figs. 10, 11 and' 12. Thus, inFigs. 10 and 11, one of the sup-v porting arms 51 is shown provided with a i 53, within which the ,shaft 39 rotates. Supported by the hub portion 53 is a hub 54 held against rotation on the shaft 39 by means of a spline fitting ,the splineway55. Carried by saidhub are a plurality of cutter arms of different kinds alternately larranged around the shaft 39.1101@ series `of these cutter. arms vmay consist simply of a number of rigid-arms 56, in the outer end of'eacjh of which vis carried a cutter 57 for cutting the coal into slabs.' Intermediately of each. pair of the cutter arms 56 is a.V shorterv arm 58 upon the outer end of which is pivotally mounted a swinging cutter arm 59 provided with a cuttr 6 in the outer end thereof. The cutter arms 59 are designedto be used for making breaking down kerfs ijfter completion of the slabbingr -kerfs 61, 62'i(see Fig, 12). asv shown in Fig. 11, each cutter 60 extends transversely of the arm 5 9 in such inanner as to adapt it to out the grooves 63 at the ends of the kerfs 61, 62.* Said cutters 6isuccessiv'lely increase in size so that when they are passed through the coal or the material to be cut, thelend of the kerf is grooved, as shown in the lower. portion #tof Fig. 12, and finally assumes the forni *shown in the upper portion port 51 and provided with vertically projecting pins 66, 67 adapted to be'movedinto and out of the path of vmovement of the projections 68 and 69 during the rotation of the cutter bars. j r

VA gear 70 keyed to the upper end of the vertical shaft 44 receives motion from the driving pinionr 14 on the motor shaft 13. A pinion 71 also keyed tothe shaft 44 meshes with a gear 72, which keyedto the vertical shaft 45. Also keyed to .the shaft 45 is a driving-pinion 73, which, by means of intermediate gears 74 and 75, transmits motion to a largegear 76, which is keyed to the shaft 39, thus driving the cutter bars 56 and'58. The gear 75 is preferably supported from one of the supports 51;

The, operation of the machine will now be readily understood andbrieflv described, is as follows: The sprockets 30 and 32 on the side rails 1 and 2 ,.when driven bv the motor 12, travel along the lower band of the endless chain 31, just as though upon a continuous rack, the forward sprocket 32 continuously disposing the links of the chain in lof Fig.`.12. .In order to provide means for ing arms 37 and 40 to correspond to any arrangement of kerfs desired. Should it be desired to raise or lower all of the cutters together, the adjusting screw 11 threaded within the platform 8 and impinging upon the cross rail 3, may be rotated to raise and lower the platform 8 relatively to the supporting base framel comprising the members 1, 2, 3, 7, etc. This havingrbeen dne, the cutter bars may be set in motion and the machine fed bodily' toward the 'coal wall by means of the pcd-chains 31.

To one side y.of the machine is mounted a chute 77, within which travels a conveyer' -78 carried by-pulleys 79 'and 80. Said con* veyer and chute are disposed directly across the path of -the rotating cutters as theV emerge 'from'the coal, so that when thecoal is broken-down during the rotary movement of the cutters, it'will be ejected in front of the lower end of the conveyer, and

as said conveyer is advance bv thetravel "of the machine, the coal will be passedrear-v sin i ivaovi m transverse shaft 84 is provided with a bevel gear 85 keyed thereto, which meshes with a bevel gear 86 on the shaft 16, from which it derives its motion directly from the motor l2.
